DETAILED DESCRIPTION

The following describes the present disclosure further in conjunction with the accompanying drawings:

Referring to FIGS. 1 to 6 , this embodiment takes an automatic hair curler as an example for description. The automatic hair curler includes a curling part 1 and a handle part 2.

The hair curling part 1 includes two splint devices 11 arranged opposite to each other, and a sleeve 12 concentrically sleeved outside the splint device 11.

The splint device 11 includes a mounting shell 111 arranged along the axial direction, and a heating plate component 112 movably mounted on the inner side of the mounted shell 111, specifically, the heating plate component 112 includes an elongated square tube heat-conducting plate 1121, and a PTC (Positive Temperature Coefficient) heating element 1122 and an NTC (Negative Temperature Coefficient) temperature control element 1123 are provided in the cavity of the heat-conducting plate 1121. An elastic member 113 is arranged between the mounting shell 111 and the heating plate component 112 so that the two sets of opposite heating plate components 112 can be attached to form a hair heating working surface 110. In this embodiment, the elastic member 113 is preferably a plurality of evenly arranged springs, and the springs provide the force for clamping the heating plate component 112; in other embodiments, the elastic member 113 may also be an elastic structure such as an elastic sheet or a silicone elastic cushion. Preferably, the heating plate component 112 is mounted to the mounting shell 111 at its two ends through a sliding buckle structure 114 that can slide along a clamping direction of the splint device 11, in this example, the sliding buckle structure 114 includes sliding slot holes 1141 along the clamping direction provided at both ends of the mounting shell 111, and sliding blocks 1142 provided at both ends of the heating plate component 112, which are respectively slidably fitted with the sliding slot holes 1141 along the clamping direction and have hooks; in other embodiments, the sliding buckle structure 114 may also be in the form of a guide post and guide sleeve matching structure with a limit feature; the sliding buckle structure 114 has a guiding function, which can make the heating plate component 112 move stably without deflection during clamping. Preferably, the front ends of the two sets of heating plate components 112 are formed with a flared guiding surface 115 for guiding hair into the hair heating working surface 110. The guiding surface 115 is convenient for moving hair from the front end of the curling part 1 onto the hair heating working surface 110.

The sleeve 12 has two oppositely arranged placement grooves 121 distributed along the axial direction, and the placement grooves 121 usually correspond to the two sides of the hair heating surface to facilitate the insertion of hair; preferably, the front end of the placement groove 121 has a hook-shaped part 122 extending laterally to prevent hair from escaping from the placement groove 121, the hook-shaped part 122 can prevent the hair from loosening from the front end of the placement groove 121 when the hair is curled.

The handle part 2 is provided with a driving motor 21 for driving the sleeve 12 or the splint device 11 to rotate around an axis, and is provided with a control circuit board 25.

When curling hair, the user only needs to clip a bunch of hair between the hair heating working surfaces 110, under the action of the elastic member 113, the hair is clamped and fixed by the heating plate component 112, and with the rotation of the hair curling part 1, the hair is wound around the outer circumference of the splint device 11 or the outer circumference of the sleeve 12 and then is combed toward the end of the hair, thus the user only needs to comb hair by holding the handle part 2 during the hair curling process. When the hair is wrapped around the outer circumference of the splint device 11 or the outer circumference of the sleeve 12, the degree of curling of the hair is different, and thus the hair can be curled into shapes of different arcs. Certainly, the sleeve 12 also has the function of heat insulation and protection to prevent the user from being scalded by the heating plate component 112 during operation. The splint device 11 can also be used for hair straightening, and the driving motor 21 does not need to be started when straightening the hair.

In a preferred structure, the handle part 2 includes a housing 22 formed with an air duct, and a fan component 23 arranged in the housing 22, the rear end of the housing 22 has an air inlet 24, and the front end of the housing 22 is connected with the curling part 1; the fan component 23 includes a motor and blades, and the mounting shell 111 has an air guiding cavity in communication with the air duct, in addition, a plurality of air outlet holes 1112 communicating with the air guiding cavity 1111 are distributed on the outer side of the mounting shell 111. The air outlet holes 1112 are provided on the outer side of the mounting shell 111, so that the heated hair can be quickly and uniformly cooled and shaped, without waiting during the combing process, and the curling operation can be completed quickly.

Referring to FIG. 4 , preferably, there is an air guiding groove 1113 corresponding to the inner side of each air outlet hole 1112, the air guiding groove 1113 is closed on the peripheral side and has an inlet 1113 a toward the rear end, and the bottom surface of the air guiding groove 1113 is a slope-shaped air guiding surface 1113 b that tapers toward the front end; a height of the inward sinking of the inlet 1113 a of each of the air guiding grooves 1113 distributed from the rear end to the front end gradually increases. The air guiding groove 1113 is provided to better guide the cold air in the air guiding cavity 1111 to each air outlet hole 1112, moreover, the closer the inlet 1113 a is to the front end, the higher the height that it sinks inward, which can avoid being blocked by the air guiding groove 1113 at the rear end, so that the distribution of the cold air blown out from each air outlet hole 1112 is more uniform.

In this embodiment, it is preferable that the splint device 11 is driven by the driving motor 21 to rotate around the axis, and the sleeve 12 is fixedly connected to the handle part 2. This method is more convenient for the design of the rotation and electrical connection structure, but also because the direction of the force on the hair is different when the hair is wound, the structure is more conducive to the winding of the hair.

In a preferred structure, a Hall switch component for controlling the rotation angle of the splint device 11 is further provided, and the Hall switch component are arranged in one group or two groups arranged symmetrically around the circumference; specifically, the Hall switch component includes a Hall sensor 251 arranged on the control circuit board 25, and one or two groups of magnets 133 that rotate with the splint device 11. When the magnets 133 are set in one group, the splint device 11 stops rotating after one rotation, and when the magnets 133 are arranged evenly in two groups, the splint device 11 stops rotating after half a rotation. The rotation angle can be conveniently and accurately controlled to avoid excessive entanglement and hair jamming.

Referring to FIGS. 7 and 8 , in this embodiment, a spacing plate 13 that can rotate with the splint device 11 is provided between the driving motor 21 and the end of the splint device 11, the spacing plate 13 has a through hole 131 corresponding to the air guiding cavity 1111 and a shielding part 132 for shielding the end of the heating plate component 112. The spacing plate 13 can rotate with the driving motor 21, and during the rotation, the cold air can enter the air guiding cavity 1111 through the through hole 131, but the end of the heating plate component 112 is blocked by the shielding part 132 to avoid cooling. Further, a conductive component 14 for electrical connection is sleeved on the driving shaft of the driving motor 21, the conductive component 14 includes a fixed ring 141 near the side of the driving motor 21, and a rotating ring 142 near the side of the hair curling part 1 and rotating with the driving shaft, the fixed ring 141 and the rotating ring 142 are electrically connected by conductive elastic pieces 143 that are in rotational contact with each other. The conductive elastic pieces 143 can maintain the contact-type electrical connection during the rotation.
